Abstract
A heat exchanger including an internal passage extending from a first inlet end to a first outlet end; a first longitudinal length extending from the first inlet end to the first outlet end; an inner surface of the passage including a first augmentation feature disposed along the first longitudinal length across the inner surface; an outer surface extending from a second inlet end to a second outlet end, the outer surface being in heat transfer communication with the inner surface; and a first region including portions of both the inner surface and the outer surface adjacent at least a portion of the first inlet end, wherein the first augmentation feature varies a cross-sectional area in a direction along the first longitudinal length and within the first region.
